BEATER, MIXER, AND [WASHER FOR EGGS, CREAM, VEGETABLES, 84.0-

T0 (117/ whom, it may concern.-

Be it known that I, WILLIAM STURMA, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Beater, Mixer, and Masher for llggs, Cream, Vegetables, &c., of which the follow- 'ing is a specification.

My invention relates to improvements in the class of beaters, mixers, and mashers for I eggs, cream, vegetables, &c., as shown in the j hwhich is ournalod on the rocking-arm It,

Letters Patent of the United States N 0. 768,086, granted to me on the 23d day of August, 1904, and consists of means for uarding the hands, &c., of the operator from contact with the couplingsfor the'phe rality of shafts employed to impart oscillatory motions to the head that works in the pan containing the material.

It further consists of means for placing the guard in inoperative position.

It further consists of a head of novel con struction, as will be hereinafter set forth.

Figure i represents a perspective view of a beater, &c., embodying my invention. Fig. 2 represents a partial plan view and partial horizontal section on line an ac, Fig. 1. Fig. 3 represents a top or plan view of a heater employed. Fig. 4 represents a section of a portion on line y y, Fig. 2.

Similar letters of reference indicate corrcsponding parts in the figures.

Referring-to the drawings, A designates a standard, and B a support or base therefor.

C designates a driving-shaft, the same being vertically mounted in the bearings D on the bracket D, which is bolted or otherwise secured in said standard A, said shaft having its front end deflected, as at E. ()n the uper end of said standard are the loose and ast pulleys F G, each of which is adapted to have a belt or band pass around the same. On the shaftC is the sleeve-II, which. is adapted to rotate with the same and rests upon the collar H, which fornis a bearing for said shaft, and mounted it on it is the lever J,

racket I ing from said lever and pivotally connected therewith is the latch K, which is adapted to engage with a piri or stud L, the latter projecting from the Bracket D, whereby the lever J, and consequently the shaft C, may be held in. elevated position, so that the belt or band shifts from the fixed ulle G to the loose pulley F, thus. rendering t te shaft (1 Depend- Specification of Letters Patent.

said sleeve N also passing through a sleeve Q,

which. is pivoted, as at It, on a bearing piece, D" at the lower portion of the bracket D.

Depending from the lower end of the shaft P is the head S, which is adapted for beating, mixing, or mashing, it entering the pan '1, (shown in dotted lines,) which pan is sustained in eithrr of the open rims U, the latter being connected by the ears V and bolts 7 with the standard A and being of different diai'nctrrs fordiilerent sizes of pans, said rims being provided with means for sustaining one on the other.

It will be seen that when the shaft C is in operation and properly lowered motion is conin'iunicated from the shaft P, and as the latter is supported in the sleeve Q after the manner of a universal joint said shaft 1 oscillatrs and forces the head S to be carried around by the same, and so sweep the interior of the pan T, thus effectively acting on the contents thereof.

Mounted on the bracket D is the bearingpiece 1)". At the portion of the bracket 1) adjacent to the coupling M is the ring X, the front end of which is divided or split, form ing the throat Y, it being seen that said ring when in its operative position is placed some what around said coupling and forms a guard for the hand of the operator, so as to prevent the same from being caught or injured by the movements of said coupling, said rim: encircling said coupling at a sulfieient distance therefrom so that as the hand of the operator moves from the pan T to the lever J, or vice versa therefrom, and it or his hand contacts with said ring the latter warns theoperator of the dangerous proximity of his hand or head to said coupling, while also removing the hand or head sufliciently therefrom. r

When it is desired to have access to said coupling, the ring is thrown up from a horizontal to an upright position, when it may be I CC ' ing to the throat Y the ring may readily pass the direction of their lengths I have their lower ends radiate from the exover the lower portion of the-shaft C and upper portion of the shaft P.

It will also be seen that the bracket D extends from the upper portion of the standard A to near the ring U, and so provides bearings for the shaft C, thering X and the oscillating arm R providing a strong structure for supporting said parts. p

,The head S is composed of a number of bladesS, extending from a centrally-connecting block or boss S which latter is connected with a shank S by which the head is attached to the operating-shaft and projects u wardly from saidblock and curved in the directionof their length, while tapering from said block to the upward terminal of the same, the sides of said blades being also in The blades S te'rior of said boss S it' being noticed that the latter is of small size in transverse direction, and said blades present broadand fiat sides to the article to be beaten, 800., throughout their extreme lengths from bottom to top, said blades alternating with the sides of the boss and standing out from the same, whereby the material'will be subjected to the beating action not only from near the shank S but also the extreme width of the blades, and so it"is dashed in and out in radial direc tion while being driven ahead.

Itwill be seen that when the head rotates it acts effectively on the material to be beaten, Whipped, &c., violently beating the same and causing effective beating, mixing, or mashing of the material which is subjected to said action, and as theblades are integral with the block or hub S they are strong in their connection therewith and being of solid material present broad closed surfaces to the material thus.

In order to hold the ring X in horizontal or operative position, the ears X, by which said ring is pivotally connected with the bearing D on the bracket 1), are connected by the cross-bar X, which is adapted to abut against said bearing as a stop, (see Fig. 4,) thus limiting the descentof'said ring and ssasoa supporting the same, as shown in said Fig. 4,

to encircle or approximately encircle said shaft having ,in its periphery a division, permitting the walls thereof to pass said shaft in being placed in inoperative position, without displacing the shaft.

2, In a beater of the character stated, a divided shaft, a bearing therefor, a coupling for the members of said shaft, a ring mounted on said bearing and adapted to encircle or approximately encircle said coupling, said ring having a throat in its periphery adapted to pass said shaftin its location in inoperative position.

3, In a beater of the character stated, a guard for the shaft thereof composed of a piece adapted to encircle or approximately encircle said shaft and pivotally mounted on a bearing so as to be removed into inopera tive position, the pivotal portion of said piece having a member adapted to form a stop assisting to support the piece in operative position and the peripheral portion thereof having a division permitting the walls thereof to pass said shaft in being placed in inoperative position Without displacing the shaft.

4. In a heater of the character stated, 'a pan-support composed of an open member, means for holding the same'in operative position and a removable rim adapted to' be placed within said support, thesame being provided with means for sustaining it thereon.

5. A rotary beater composed of a central boss and blades, the latter radiating from said boss, extending upwardly therefrom and having flat sides, said lades alternating with. the sides of said boss and forming a continuity of said sides from or approximately from th e'lrotto ms to the tops thereof.
